我们提出了一种高效、便捷的3,8-二溴菲啶衍生物及其共轭聚合物的合成方法，并证明含菲啶的共轭聚合物可用作发光化学传感器材料。通过钯催化的 Suzuki-Miyaura-Schluter 缩聚反应 (SMSPC) 合成了高分子量聚菲啶-co-芴 (P1, P2) 和聚(菲啶-co-对亚苯基) (P3)。这些含菲啶的聚合物在溶液中具有高量子产率，并且对菲啶环的质子化和去质子化表现出可逆的光学响应。
We present an efficient and convenient synthesis of 3,8-dibromophenanthridine derivatives and their conjugated polymers and demonstrate that phenanthridine-containing conjugated polymers can be used as luminescent chemosensor materials. High molecular weight poly(phenanthridine-co-fluorene)s (P1, P2) and poly(phenanthridine-co-p-phenylene) (P3) were synthesized by palladium-catalyzed Suzuki-Miyaura-Schluter polycondensation (SMSPC). These phenanthridine-containing polymers are of high quantum yields in solution and show reversible optical response to protonation and deprotonation of the phenanthridine rings.
